I know this is the wrong forum but I'm guessing it's the most popular one and I need an answer NOW

 

I'm trying to change my water pump, so far I've removed the radiator shroud, radiator, radiator hoses, etc.

 

I now have the fan in my way

 

There are 4 bolts attaching the fan to the pulley.

 

I try to loosen a bolt, the pulley moves

 

I reattached the serpentine belt, hoping it's hold it, but the pulley still turns.

 

How do I get the damn fan off????

 

And since I have the radiator out, should I go ahead and replace it with another one? Someone said factory it's a 2 chamber and I should get a 3 chambered one?  How much should I expect to pay for a new radiator?

 

Well thanks for any help guys.  BTW it's an 88 GMC Jimmy S15 2.8l auto

 

I need to get this done today so fast replies are very much appreciated.

never mind, i just used some common sense and tightened the belt tensioner which in turn held the pulley in place while i broke the nuts free

 

now i have clear access to my water pump, but there's a power steering bracket blocking 2 of the screws, a bracket i paid someone $140 to put on and now i have to take it off somehow :ticked off:

 

don't have the tools now.. need a special star screwdriver for the screws on the water pump and i need to get the pulley off the power steering pump to get that bracket off...

 

i hate my life

Put a box end wrench on one of the bolts where it will press against the pulley.  Then use another wrench/ratchet to loosen one of the other bolts.  On the next to the last bolt, leave it threaded in 3-4 threads and loosen the last one.

I have two words for you.  IMPACT GUN!  Now you know why mechanics get paid what they do. Working on cars and trucks is a pain in the tail, and when you don't have the right tools or know-how it is even worse.

    • Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.
    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
